# Azure Kubernetes

Plan and deploy production-ready AKS clusters, focusing on critical Day-0 decisions (hard to change later) versus Day-1 features (configurable post-creation).

## Initial Assessment

Gather requirements around:

- Environment type (dev/test vs. production)
- Target region
- Expected scale
- Networking requirements
- Security posture
- Observability needs

## SKU Selection

**Default to AKS Automatic** for most workloads unless specific customization needs justify Standard SKU's additional management overhead.

| SKU | When to Use |
|-----|-------------|
| **AKS Automatic** | Most workloads — managed node provisioning, auto-scaling, sane defaults |
| **AKS Standard** | Advanced networking, custom node configs, specific compliance requirements |

## Day-0 Decisions (Networking)

These are hard or impossible to change after cluster creation:

| Component | Recommendation | Rationale |
|-----------|---------------|-----------|
| **Pod IP model** | Azure CNI Overlay | Recommended for most cases; avoids IP exhaustion |
| **Dataplane** | Azure CNI with Cilium | eBPF-based performance |
| **Ingress** | App Routing with Gateway API | Default standard |
| **DNS** | LocalDNS on all node pools | Performance improvement |

## Security Framework

- **Authentication:** Microsoft Entra ID for all cluster authentication
- **Secrets:** Azure Key Vault via Secrets Store CSI Driver
- **Policy:** Azure Policy with Deployment Safeguards enabled
- **Images:** Signed image policies via Azure Policy and Ratify

## Observability Stack

| Component | Service |
|-----------|---------|
| Metrics | Managed Prometheus |
| Logs | Container Insights |
| Dashboards | Grafana |

## Reliability & Scale

- Deploy across **3 Availability Zones** for HA
- Use **Standard tier** for 99.95% SLA
- Enable **Ephemeral OS disks** and Azure Linux for performance
- Use **Node Auto Provisioning (NAP)** for cost-efficient scaling

## Cost Controls

- **Spot node pools** for batch workloads (up to 90% savings)
- **Stop/start** for dev/test clusters during off-hours

## MCP Tools & CLI Fallback

The skill uses MCP tools to discover available AKS functionality and falls back to Azure CLI when needed. It never exposes secrets or subscription identifiers in output.

## Installation

```bash
npx skills add https://github.com/microsoft/azure-skills --skill azure-kubernetes
```
